Will a 500mm 20x20 V-Rail handle a 70oz Nema 17 without any deflection from true? One thing I forgot all about when I designed my printer I am about to build (just waiting on the 500mm 20x20 V-Rail to go back in stock). How about as loading bearing so think of a 70oz Nema 17 on top of the V-Rail standing vertically?
